CMPE

The PointEach of you has declared a major of BTA, IS,

CMSC, or CMPEYou can change your majorIt’s better to change your major sooner rather

than laterWe want to help you make the right choice for

youIf we do our jobs, you’ll have a much clearer

idea of what major you want, what you can do with it, and why it’s right for you

Semester Game Basic scenario

Player makes choices about how to allocate time in each of 15 weeks Game simulates outcomes

Possible choices for outcomes Happiness Grades Wealth

Possible choices for time (for 168 total hrs/wk) Going to class Paying attention during class Leisure activities (solitary and with others) Studying alone Working Study in groups Visiting academic resources Self care (sleeping, eating, exercising, etc.)

Modeling Exercise 1 In your group, discuss the following choice:

Hours spent studying and working on assignments by yourself

For this choice, Specify a reasonable range (might depend on number of

credits taken this semester) Model the effect on each outcome with a mathematical rule

E.g. “for each hour spent over 100, happiness goes down by 5%” or “for each hour spent, grades go up by 50%”

Be prepared to share your model and argue why it is superior to other models.

Competing models for hours spent studying…

For every hour over 22, happiness goes down 12% and grades go up 2%

For every hour over 3 per day, happiness goes down 15% For every hour over 24.5 per week, happiness goes down 1.05% For every hour, happiness goes down .7% and grades go up

2.3% For every hour over 4 per day, happiness goes down 11% and

grades go up 3% Reasonable range 10-15 hrs per week For every hour over 15, happiness goes down 5% and grades go

up 2%

Initial rulesChoice Name Expected range Impact

number of credits of classes 0-21 no direct impact

number of hours worked at outside job 0-168 for each hour worked, increase total wealth by $5 (to figure in

taxes and expenses)

hours spent attending class 0-#credits if hours < #credits, decrease grade potential by (100*(credits - hours)/(2*credits)); increase happiness by 1% for each hour of class missed

percentage of class spent actively engaged 0-100

if percentage < 100, reduce value for “hours spent attending class” by (100 - percentage)% before using it in grades and happiness calculations described above

hours spent studying and working on assignments 0-168

if hours < 3*credits, decrease grades potential by (100*(3*credits - hours)/(3*credits)); if hours > 4*credits, decrease happiness by 20%

hours spent participating in study groups 0-5 for each hour (up to a max of five), increase grades potential by

2%

hours spent on visits to academic resources 0-3 for each hour (up to a max of three), increase grades potential by

5%

hours spent taking care of self 0-168 if hours < 70, reduce grades and happiness potential both by

(100*(70-hours)/(4*70))

hours spent on solitary leisure activities 0-168 for each hour, increase happiness potential by 2%

hours spent on activities with other people 0-168 for each hour, increase happiness potential by 3%

Modeling Exercise 2In your group, discuss two of the choices in the

game (you’ll be assigned two)For this choice,

Specify a reasonable range (might depend on other variables)

Model the effect on each outcome with an equationLook at the initial rule for inspiration, but don’t be

bound by it Be prepared to report out your model and argue

why it is superior to the initial rule.
